An improved range variant alternately called the Ro Dong-1, Scud D and Scud Mod D. Characteristics are identical to those above, except that it carries a 1,676-lb (760-kg) warhead and has a range of up to 810 nm (932 mi, 1,500 km).
No Dong-2
Variant with a longer range, an improved guidance system and a smaller warhead. The No Dong-2 likely served as the design used by the North Koreans for the Iranian Shahab-3 and Pakistani Gauri (Hatf-5 , see separate record) missile programs. The Shahab-3 and Gauri are probably not exact copies of th e No Dong-2 since the North Koreans likely made modifications to the missile's dimensions and weight depending on the user nation's specifications.
According to Jane's Strategic Weapons Systems, dated January 2009, the North Korean No Dong 2 might also be the North Korean Musudan missile.
